Update Data

Information about Health Care, Services, Providers and Professionals which are being showed on mainly comes from the datasets published by Centers for Medicare & Medicaid Services (CMS), and by National Plan & Provider Enumeration System (NPPES), under the FOIA-disclosable policies ( ). That is means:

  • The information being disclosed on the NPI Registry and in the downloadable files are FOIA-disclosable and are required to be disclosed under the FOIA and the eFOIA amendments to the FOIA. There is no way to ‘opt out’ or ‘suppress’ the NPPES record data for health care providers with active NPIs.

  • The NPPES Data Dissemination Notice and outreach documents from CMS encouraged health care providers to review their FOIA-disclosable NPPES data and edit it as necessary and to remove, if they wished, sensitive data from FOIA-disclosable fields that were furnished on an optional basis (i.e. data that were not required to be furnished in order to apply for an NPI). Many health care providers have taken some or all of these actions.
